Abstract: The production performance of 14 varieties of annual ryegrass was studied in Ya’an in the southwest of Sichuan province. The growth rates of the new lines YA03 and YA08 were faster than Jumbo and Aubade. From 2011 to 2013, the yields of the new line YA17 were the highest, and YA03 also had advantages in yields from the first three cuts. The fresh yield of YA03 achieved 12994 kg/ha on average, 11.50% to 15.66% more than Changjiang No.2, Tetragold and Aubade. The hay yield was also greater by 9.47% to 12.82%, achieving 98973 kg/ha. In addition, Aubade and YA03 had very rich leaves. There were no significant differences of the phenology and the main nutrient contents among the 9 tested varieties. Therefore the new lines YA17 and YA03, with their higher yields and richer leaves, are more suitable for planting in the southwest of Sichuan province.
